Abstract
The invention discloses an insecticidal compounded agent used for controlling homopteran pests, which has the active ingredients of pymetrozine and carbamate insecticides, the weight ratio and better weight ratio of the pymetrozine and carbamate insecticides are respectively 1:0.1 to 20 and 1:0.5 to 20. After the two active ingredients are compounded, by using different mechanisms of action for mutual complementary advantages, the compounded agent has obvious synergy, excellent control efficiency to the homopteran pests, simultaneously, can control the pests which are resistant to other agents, with safe usage and low cost.
Description
technical field [0001] The invention relates to an insecticidal pesticide, in particular to a compounded insecticidal pesticide. Background technique [0002] Homoptera is a relatively large group of agricultural pests. It is characterized by many types, large numbers, strong fecundity, large morphological changes, piercing and sucking mouthparts, and all feed on plant juices. Many of them can spread plants. Viral diseases are important agricultural pests. [0003] Imidacloprid is a new type of nicotine insecticide following organophosphorus and pyrethroids. It mainly controls Homoptera pests, including planthoppers, leafhoppers, whiteflies, aphids, scale insects, etc. It has high efficiency, The characteristics of broad spectrum, good systemic absorption, long residual period, stomach toxicity and contact action make it easy to control a variety of Homoptera pests. However, long-term dependence on single use increases the resistance of Homopteran pests such as planthopper...
